Two Forms of Division Profile in Spinach Chloroplasts

Nature New Biology volume 235, page 142 (1972)Cite this article

Abstract

CHLOROPLAST division is generally thought to take place by constriction (fission)1–7. Division may also occasionally occur by the growth of a central baffle before separation8–11. Usually only one type has been observed for a given tissue although searches have been made for the alternative form. The present communication, forming part of a study on the effect of light and dark treatments on cultured leaf disks, describes the ultrastructure of spinach chloroplasts which exhibit both dumb-bell and central baffle profiles suggestive of division.
